lavc/riscv : depend on RVB and simplify accordingly
27 juillet 2024, par Rémi Denis-Courmontlavc/riscv : depend on RVB and simplify accordingly
There is no known (real) hardware with V and without the complete B
extension. B was indeed required in the RISC-V application profile from
2022, earlier than V. There should not be any relevant hardware in the
future either.In practice, different R-V Vector optimisations in FFmpeg already depend on
every constituent of the B extension anyhow, so it would not work well.- [DH] libavcodec/riscv/aacencdsp_init.c
